DANGER
GROUND FAULT MONITORING DISABLED, NO ERROR DETECTION
Setting this param eter to
[Bus & M ain
]
(Main)
deactivates ground fault m onitoring.
•
Only use this parameter after a thorough risk assessment in com pliance with all regulations and s tandards
that apply to the device and to the application.
•
Im plem ent alternative ground fault m onitoring functions that do not trigger automatic error responses of the
drive, but allow for adequate, equivalent res ponses by other m eans in com pliance with all applicable
regulations and standards as well as the ris k as sessment.
•
Com m ission and tes t the sys tem with ground fault m onitoring enabled.
•
During com m issioning, verify that the drive and the sys tem operate as intended by perform ing tes ts and
sim ulations in a controlled environment under controlled conditions.
Failure to follow these instructions will result in death or serious injury.
